Odroid C2 freezes when loading OS

Post by blackride »

Hi. Odroid C2 hangs on first boot of OS Coreelec. The first boot is when Odroid C2 is turned off before that for about 15 minutes or more. At first I sinned on microSD cards, then on OS LE / SE. However, this happens with any card and any LE / CE version.
Now I'm thinking about a 3A power supply. I connect it through the DC connector. But I'm not sure if the power supply is to blame. Because this only happens when there is a prolonged power outage and only at the first start. After that, I can turn it on / off at least much as possible and no hangs are observed.

Please help me find the reason. Maybe some kind of stabilizer or transistor is to blame?

Flashing this Ubuntu image for testing stability with your hardware or PSU configuration.

Thank you, but..

I soldered the "alternative power" (two pins on the board, next to the dc connector). And I don't see any more freezes. :)
I have one question. Why did hardkernel install such a small dc connector? :?: :?: :?:
It was possible to initially put the connector like the C4 odroid (5.5mm x 2.1mm).

Most likely the C2 inherited C1's connector, in order to reuse the same PSU and lower costs of production/stock/upgrades
